Engineered specifically to meet the strict temperature and humidity parameters of fresh flowers and premium tea leaves.
Designed for delicate floriculture, maintaining 1°C to 3°C with high relative humidity to prevent petal dehydration.
Optimized for tea leaf storage, controlling moisture content below 6% to prevent oxidation and mold growth.
Features variable speed fan control and energy-efficient heat exchange for continuous, stable microclimate operations.
Enables independent temperature zone management, ideal for facilities storing both fresh flowers and dried tea leaves.
The global floriculture and specialty tea industries are experiencing an unprecedented surge in demand. Consumers worldwide now expect premium, freshly cut flowers and high-grade tea leaves to be available year-round, regardless of regional seasons. However, both of these agricultural products are highly perishable and biochemically sensitive to post-harvest environments. According to industry research, post-harvest losses in the flower supply chain can reach as high as 30% to 40% due to poor temperature control, while tea leaves frequently lose their premium valuation due to moisture absorption and subsequent chemical degradation. This is where Unite Refrigeration steps in, redefining the standards of botanical preservation.
In the modern agricultural business landscape, standard cold storage is no longer sufficient. Traditional refrigeration systems often focus solely on lowering the temperature, which can inadvertently strip moisture from the air, causing cut flowers to wilt, or fail to control humidity levels precisely enough, leading to mold in tea leaf storage. The industry has shifted toward Precision Climate Storage. This approach treats cold rooms as dynamic microclimates where temperature, relative humidity (RH), and airflow velocity are continuously monitored and adjusted. By implementing Unite Refrigeration's advanced technology, commercial growers, wholesalers, and specialized distributors can significantly extend the vase life of flowers and preserve the essential oils, catechins, and volatile compounds in tea leaves.
Furthermore, sustainability and energy efficiency have become central to the business strategy of cold chain operators. With rising energy costs and stringent environmental regulations on refrigerants, businesses are actively seeking refrigeration partners who offer high COP (Coefficient of Performance) systems. Unite Refrigeration addresses these market demands by integrating smart digital controls, variable-frequency drives, and eco-friendly refrigerants, ensuring that climate storage facilities achieve maximum preservation efficiency with minimal carbon footprint.
Exploring the unique biological requirements and refrigeration engineering solutions for both delicate industries.
Once cut, flowers enter a phase of rapid senescence. To slow down their metabolic rate and prevent the production of ethylene (a natural aging hormone), cut flowers must be quickly cooled to their optimal storage temperature—typically between 1°C and 3°C for temperate flowers, and slightly warmer (10°C to 12°C) for tropical varieties. However, the critical challenge is relative humidity. If the RH drops below 90%, transpiration accelerates, causing the petals to lose water, curl, and wilt.
Unite Refrigeration designs systems with large-surface-area evaporators and low air velocity. This configuration prevents the air from stripping moisture from the flowers, maintaining an ideal 92% to 95% RH without causing condensation on the petals, which could otherwise lead to botrytis (grey mold). Our smart controllers also manage air circulation rates to ensure uniform temperatures throughout the storage room, eliminating hot spots that accelerate decay.
Unlike fresh flowers, dried tea leaves are highly hygroscopic; they readily absorb moisture and odors from the surrounding environment. If tea leaves absorb moisture and their water content rises above 7%, the chlorophyll and polyphenols undergo rapid oxidation, turning green tea brown and destroying its fresh, grassy aroma. For premium teas like green tea, white tea, and lightly oxidized oolongs, long-term storage requires low temperatures (0°C to 5°C) and strictly controlled low humidity (under 50% RH).
Conversely, post-fermented teas like Pu-erh require a controlled aging climate where temperature and humidity are balanced to allow slow, beneficial microbial fermentation without mold growth. Unite Refrigeration provides customized dual-action climate control systems that can dehumidify or humidify as required, ensuring that each variety of tea is preserved in its optimal biochemical state, retaining its market value for years.

The future of botanical climate storage lies at the intersection of artificial intelligence and thermodynamic precision. As global supply chains become more complex, the integration of IoT (Internet of Things) devices within refrigeration systems is transitioning from a luxury to an absolute necessity. Real-time monitoring of temperature, relative humidity, and ethylene levels allows operators to dynamically adjust storage conditions before any spoilage occurs. Unite Refrigeration is at the forefront of this revolution, developing systems that incorporate predictive maintenance algorithms and remote cloud-based management tools.
Another major trend is the adoption of green refrigerants. In alignment with global environmental accords, there is a strong push to phase out traditional HFCs in favor of natural refrigerants like CO2 (R744) and hydrocarbons. These eco-friendly alternatives not only have a negligible global warming potential (GWP) but also offer excellent thermodynamic properties, particularly in low-temperature applications. Unite Refrigeration's R&D team is continuously optimizing our condenser and evaporator designs to maximize heat transfer efficiency with these next-generation refrigerants.
Finally, modular and flexible cold room designs are gaining traction. Businesses need the ability to quickly scale up or reconfigure their storage spaces depending on seasonal harvests. Our modular multi-zone condensing units allow operators to easily switch a storage room from a high-humidity flower preservation environment to a low-humidity tea curing setup, providing unmatched operational flexibility and maximizing return on investment.
